Mold Inspection

Mold hides. It grows behind walls, under flooring, inside HVAC systems, and in ceiling cavities — often invisible to the naked eye until the contamination is extensive. A professional mold inspection identifies where mold is growing, how far it has spread, and what is causing it — information that is critical for effective remediation.

A mold inspection answers three questions that a visual walkthrough cannot: is mold present in the air and on surfaces, how far has it spread beyond what is visible, and what moisture condition is feeding it. The answer to the third question matters most, because mold is a symptom of moisture. Find the leak, condensation, or humidity problem, and you have found the root cause. Remove the mold without fixing the moisture, and it will return.

Why Professional Mold Inspection Matters

Mold is more than a cosmetic issue. It affects air quality, structural integrity, and health. Professional inspection matters because:

• Hidden mold is common — up to 70% of mold contamination is not visible during a visual walkthrough
• Air sampling reveals what you cannot see — elevated spore counts indicate mold behind surfaces
• Moisture is the root cause — without finding and fixing the moisture source, mold will return
• Type matters — some mold species are more hazardous than others; identification guides the remediation approach
• Documentation is critical — insurance claims and real estate transactions require professional reports

Our Mold Inspection Process

Step 1 — Visual Assessment

A certified inspector conducts a thorough visual inspection of the property, looking for:

• Visible mold growth on surfaces
• Water stains and discoloration
• Peeling paint or wallpaper (signs of moisture)
• Warped or buckled materials
• Condensation on windows or pipes
• Musty odors

Step 2 — Moisture Mapping

Using pin-type and pinless moisture meters, we test building materials throughout the property. Elevated moisture readings indicate where mold may be growing — even if it is not visible.

Step 3 — Thermal Imaging

A FLIR thermal camera scans walls, ceilings, and floors to detect temperature differences caused by moisture. Wet areas appear cooler than dry areas, revealing hidden moisture behind surfaces.

Step 4 — Air Sampling

We collect air samples from both affected and unaffected areas using calibrated air sampling pumps. Samples are analyzed by an accredited laboratory to determine:

• Spore count — how many mold spores are in the air
• Species identification — what types of mold are present
• Concentration comparison — indoor vs. outdoor spore levels

Elevated indoor spore counts compared to outdoor levels indicate active mold growth inside the property.

Step 5 — Surface Sampling (if needed)

When visible mold is present but type is uncertain, we collect surface samples (tape lift or swab) for laboratory analysis. This identifies the specific mold species and guides the remediation protocol.

Step 6 — HVAC System Inspection

Mold often grows inside HVAC ductwork, drip pans, and coils — especially after water damage. We inspect the HVAC system for contamination, as ductwork mold can distribute spores throughout the entire building.

Step 7 — Report and Recommendations

We deliver a detailed inspection report that includes:

• Locations and extent of mold contamination
• Moisture source identification
• Air and surface sampling results with lab analysis
• Photographs of affected areas
• Recommended remediation protocol (following IICRC S520)
• Estimated scope of work for remediation

When to Get a Mold Inspection

• After any water damage — mold can begin growing within 24–48 hours of water exposure
• Musty odors — a persistent musty smell indicates mold may be hidden
• Visible growth — even small patches warrant a professional assessment to check for hidden spread
• Health symptoms — chronic allergies, respiratory issues, or headaches that improve away from home
• Real estate transactions — pre-purchase inspections or mold disclosure requirements
• Insurance claims — documentation required for mold coverage under homeowner policies
• Post-remediation verification — confirm that mold removal was successful

Common Hidden Mold Locations

Mold follows moisture. These are the locations where hidden mold most commonly develops:

• Behind drywall — plumbing leaks and condensation in wall cavities
• Under flooring — water trapped beneath tile, hardwood, or laminate
• Above ceilings — roof leaks and HVAC condensation in ceiling cavities
• Inside HVAC systems — ductwork, drip pans, and evaporator coils
• Behind baseboards — water wicking along wall cavities
• In crawlspaces — foundation seepage and poor ventilation
• Around windows — condensation and failed flashing
• Inside wall cavities — slow plumbing leaks that have gone undetected

Mold Inspection Cost Guide

Service Item	Typical Cost Range	What’s Included
Visual inspection	$150 – $350	Walkthrough, moisture mapping, thermal imaging
Air sampling (per sample)	$75 – $150	Calibrated pump, lab analysis, spore count
Surface sampling (per sample)	$50 – $100	Tape lift or swab, lab species identification
HVAC inspection	$100 – $250	Ductwork, drip pan, coil inspection
Written report	Included	Lab results, contamination map, recommendations

Expert tip: One air sample is not enough to draw conclusions. We always take samples from the affected area and a control sample from outside the home. Comparing indoor spore levels to the outdoor baseline is what separates a real indoor problem from normal outdoor mold in the air.

Mold Categories and Health Risks

Category	Common Species	Health Risk	Remediation Level
Allergenic	Cladosporium, Penicillium, Alternaria	Allergic reactions, respiratory irritation	Level 1 — isolated areas
Pathogenic	Aspergillus, Fusarium	Infection risk for immunocompromised individuals	Level 2 — moderate areas
Toxigenic	Stachybotrys (black mold), Chaetomium	Mycotoxin production; serious health concerns	Level 3 — large areas or HVAC contamination

DIY Mold Testing vs. Professional Inspection

Home mold test kits are widely available, but they have real limitations:

• They cannot find hidden mold — a home kit samples the air in one room and gives no moisture mapping or thermal imaging to locate hidden growth behind walls.
• Results are hard to interpret — home kits show whether spores are present but not how they compare to a proper outdoor baseline or whether the species requires special handling.
• No remediation plan — a lab report without a moisture map and a written remediation protocol leaves you without the information that actually drives the fix.

A professional inspection provides the full picture: where the mold is, why it is there, what species it is, and what to do about it. That documentation is also what insurance and real estate transactions require.

Our Inspection Standards

All inspections follow:

• IICRC S520 — Standard and Reference Guide for Professional Mold Remediation
• IICRC S500 — Standard and Reference Guide for Professional Water Damage Restoration
• EPA guidelines — mold assessment and remediation standards
• ANSI/IICRC S520 — professional mold inspection protocols

Mold Inspection by State

Mold issues vary widely by region because climate drives moisture. In humid southern and Gulf states, high year-round humidity and frequent rain make mold a persistent concern, and inspections often find growth in crawlspaces, attics, and around HVAC systems. In cold northern states, mold commonly follows burst pipes, ice dam leaks, and winter condensation on windows and walls. In coastal areas, salt air and storm-driven moisture accelerate growth behind siding and under floors. In arid southwestern states, mold is less common but still appears after monsoon roof leaks and plumbing failures. Our local inspectors know the patterns of their region and look for the moisture paths that matter there.
